The fakes do a DECENT job, but you can still spot the edges...
These fakes coming out may be more convincing, but then, even if a real video comes out, it will be called a deep fake.
I could see these deep fake videos requiring some serious server time to get the job done too... I don't think too many people are going to use their desktop running for like a month just to build a 30 second clip.
I like your plan to use the block chain technology, that would be a great way to establish a YouTube replacement, and would help protect content creators.
I agree bmanmcfly, currently the fakes are still quite easily discernable, but who knows how much better than can get?
What's amazing is how much is already on the net just from every day people using their computer GPU's, imagine what can be done on an institutional super computer that has significantly greater resources!
